Chapter 15 Hands and feet are very fast (, crazy for votes

The petri dish is used to cultivate microorganisms. The shape is a very low cylindrical glassware with a glass lid on it. When cultivating microorganisms, pour the prepared medium into the petri dish, and after the medium solidifies, inoculate the microorganisms on it. Therefore, when the petri dish is used up, it is still relatively troublesome to deal with it. First of all, the medium with solid glue in the petri dish should be poured out. Because the medium is generally in the shape of solid glue, it is easy to stain the glass and it is difficult to clean. It needs to be brushed repeatedly. Not only that, there are often numbers under the petri dishes, and they also need to be scrubbed off. Therefore, the cleaning of petri dishes is relatively time-consuming and labor-intensive. As for sterilization and disinfection, it is another process of the petri dish. It is necessary to dry the washed petri dish, and then wrap it in more than a dozen cylinders of things such as newspapers or kraft paper, and put them into a high-pressure disinfection pot for disinfection. More than a dozen can be wrapped up, of course, it is also a lot of work.

So when Su Lingfei's words came out, she just wanted Zhang Weidong to come to work overtime at night.

"Empt, no problem!" Zhang Weidong nodded calmly.

Su Lingfei thought that her words would definitely force Zhang Weidong to jump up and down, at least with a sad expression. Of course, it would be better if she could beg her to raise her hand. Unexpectedly, Zhang Weidong still looked calm, as if this kind of vessel was nothing to him.

"Then please trouble Mr. Zhang. Remember to hurry up. I'll use it tomorrow." Su Lingfei smiled and said with a smile on her face, but she gritted her teeth secretly in her heart and said that she would die if she would suffer? What's so cool? What are you going to pull? Well, this is your own trouble. Auntie wants to see what time you will be busy!

"Don't worry, this will not make it difficult for me." Zhang Weidong glanced at the utensils on the table and said lightly.

Zhang Weidong is not a fool. Now of course, he can see some of Su Lingfei's intentions. However, since he is one of the members of the research group, Zhang Weidong doesn't think it's a big deal. After all, someone has to do the cleaning, right? In this kind of thing, Zhang Weidong never cares about a woman, and it is really difficult for him.

Seeing that Zhang Weidong still looked cool and awesome at this time, Su Lingfei almost couldn't help walking away, revealing the "insidious" true face. However, in the end, Su Lingfei still smiled and said, "Well, go ahead. I still need some buffer solution."

After saying that, Su Lingfei went to another table and began to configure the buffer solution, but the beautiful peach blossom eyes secretly peeped at Zhang Weidong.

At this look, Su Lingfei was immediately dumbfounded!

Zhang Weidong's hands seemed to have magic, casually grasping the mountain-like petri dish, and a petri dish was just picked up between his fingers. With two hands and ten fingers, he grabbed eight petri dishes neatly and orderly for him.

It's nothing. What surprised Su Lingfei most was that Zhang Weidong's hands gently shook on the trash can. The medium that was usually difficult to get down was like a round cake-shaped jelly, falling into the trash can. As soon as the culture medium fell off, the bottom of the petri dish turned out to be clean and could not see any residue.

Originally, it would take an hour or two to clean up the culture medium with four or five hundred petri dishes, but just as Su Lingfei was stunned, Zhang Weidong had already dealt with fifty or sixty. At this rate, it is estimated that in less than five minutes, Zhang Weidong could train four or five or five. The culture medium in the dish has been cleaned up.

In fact, Zhang Weidong doesn't want to be too shocking. He just uses his hands a little dexterity. Otherwise, he really has to spare no effort to do his real power. It's not a matter of minutes to clean up these culture media.

However, Zhang Weidong was extremely restrained, and Su Lingfei was still stunned. Finally, she couldn't help it. She walked over and stretched out her jade-like finger to pick up the petri dish, but she couldn't pick up four with one hand, let alone pick up four easily like Zhang Weidong.

Unconvinced, Su Lingfei, who did not believe in evil, took a petri dish again and shook it hard on the trash can, but she shook her wrist and did not shake the culture medium down. Finally, Su Lingfei, who was depressed and helpless, took the petri dish and gently smashed it down on the edge of the trash This time, the culture medium was finally taken down, but the wall of the petri dish was covered with residue. Like Zhang Weidong, every petri dish that shook by him was not stained with any residue and was clear.

Su Lingfei naturally didn't believe in evil. She took another petri dish and tamped it up, but the result was still the same. She was so angry that she knocked hard on the trash can with the petri dish.

With a bang, the petri dish finally couldn't stand Su Lingfei's "severe" beating and broke.

"You are so awesome! Well, don't make trouble. Be careful to cut your hand. You can't learn this trick. Seeing that Su Lingfei, a poor woman, seemed to have hit an evil and couldn't get along with a petri dish, he couldn't help frowning slightly and mercilessly.

What? Did he say I was in trouble? Su Lingfei was so angry that her face turned blue, but she looked down at the broken petri dish in her hand. No, she could break the petri dish by pouring a culture base. This is not a mess. Thinking about it, Su Lingfei really had the impulse to pick up the glass fragments in her hand and cut it on her wrist.

Let's wait and see. Auntie doesn't believe that you can clean so many things in one morning! Finally, Su Lingfei threw the glass fragments in her hand into the trash can with hatred, returned to her own table and continued to configure the buffer solution.

However, Su Lingfei's buffer solution had not been ready, and she was immediately stimulated again. After quickly cleaning up the culture medium, Zhang Weidong turned on the two faucets on the sink at the same time, with four petri dishes in each hand as before. Then he moved his hands with ten fingers, and eight petri dishes quickly turned over in his hand under the faucet. The action is really fast and smooth, much more wonderful than acrobatics. After a while, the eight petri dishes were washed at one time, and then Zhang Weidong raised his hand.

Shhhh! Just like playing Frisbee, eight petri dishes came out one after another, and then the opening was stacked diagonally towards the next one, neatly arranged in a row on the tray.

How is this possible? Su Lingfei opened her eyes wide, and her eyes turned quickly back and forth with the petri dishes flying in the air.

In a few minutes, a tray was neatly placed with nearly a hundred petri dishes. What's more exaggerated is that there are no drops of water hanging on the glass wall of the petri dish, which is a sign that the glassware is clean. Of course, it is clear that Su Lingfei is engaged in scientific research.

Fortunately, Zhang Weidong had a lot of rules when washing beakers and conical bottles later, but even so, his movements were still many times faster than ordinary people.

So at noon, the mountain of utensils piled up on the table were cleaned and placed neatly by Zhang Weidong. As long as you come in the afternoon and sterilize and disinfect them, even if the great work is completed. Before, Su Lingfei was full of calculations. She thought that Zhang Weidong had to wash so many things alone, so she had to be busy until the afternoon. If sterilization and disinfection were included, I'm afraid she would have to work overtime at night.

Looking at Zhang Weidong's hands washing, his buttocks twisted, and pulling his hands away very coolly, Su Lingfei's heart surged with a trace of admiration for Zhang Weidong unruly. At the same time, what surged up was more unwillingness and depression.

"What are you going to pull, it's just faster!" Su Lingfei rubbed her hands fiercely and said with hatred. However, although she said so, she knew in her heart that Zhang Weidong was definitely not just a little faster. Because of this, she was even more depressed.
